Purpose

To evaluate one-year results of a phaco-trabeculectomy technique assisted by polypropylene suture placement.

Setting

CEO, Oftalmología Rosario. Rosario, (Santa Fe) Argentina.

Methods

A prospective, multicenter, nonrandomized case series study was performed. Patients with open-angle glaucoma operated by a modified phaco-trabeculectomy technique between November 2022 and November 2023  were included.

A suture made with 6.0 polypropylene was used, performing a shape of the OMEGA letter, with three anchors in the sclera, seeking a mechanical spacing function. The main outcomes were intraocular pressure (IOP) and the amount of topical hypotensive drugs used before surgery and at 12 months after surgery. Efficacy was considered to be achieved when IOP was reduced by more than 20% compared to baseline, with a decrease in one or more antihypertensive drugs.

Results

Twenty-six eyes of 26 patients were included. The mean IOP was 26.4 ±8.6 mmHg (18-51) preoperatively and 12.8 ±3.1 mmHg (7-18) postoperatively, achieving a mean decrease of 13.6 mmHg, twelve months after surgery (p<0.001). Regarding the amount of hypotensive drugs, preoperatively, it was 3.3 ±0.5 (3-4) and decreased postoperatively to 0.7 ±0.9 (0-2). All cases achieved the efficacy criteria.

Conclusions

The modified phaco-trabeculectomy technique using a polypropylene suture effectively decreased IOP in eyes with open-angle glaucoma, maintaining good results one year after surgery.
